I've setted up a Xen server with kernel 2.6.18-r12 with 2 SATAII disks |
4 |
of 750Go and with the following partitions scheme : |

dom0 ~ # sfdisk -l |

Disk /dev/sda: 91201 cylinders, 255 heads, 63 sectors/track |

Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 |

I've created some guests using LVM logiccal volumes on /dev/md3 and |
53 |
formatted with XFS filesystem. Sometimes, i've this messages in dmesg on |
54 |
dom0 : |
55 |
raid0_make_request bug: can't convert block across chunks or bigger than 64k |
56 |
|
57 |
After that bugs, there is many Input/Output errors in the guest, and so |
58 |
broke his gentoo installation so make me impossible to read the guest |
59 |
system logs. Any help would be greatly appreciated as this server |
60 |
actually host my primary DNS server and so i can't reinstall it from |
61 |
scratch. |

Many thanks in advance. |
